Khan Academy: The Hour Of Code

Hi there, how are you?

Today Ivana Saggion and I are talking about something called the hour of code. This is something we learned about at a great website called Khan Academy. This is, in our opinion, the best website for learning any topic you want to learn about. So go on, visit it, I'm sure you're going to love it.

For the class of informatic, we entered to Khan Academy and logged in. The teacher gave us a lot of things to do, we had to sign up in Khan Academy and complete the challenges/projects given by the program.

Here is a challenge we had to complete:

It has basic and simple codes that helps us to do all the projects!

For example this project...

If you’d like to see the entire code: <Code>

And here, we have some important concepts you need to know if you are interested in coding:

When you use coding to, for example draw a snowman, you use specific commands or functions. This is a very important concept you need to know if you want to code. We could say, that a command is a set of words that gives the server a simple instruction he knows how to follow. For example, if we use the command known as ellipse, type some numbers inside the parenthesis and write a semicolon at the end, the server will immediately know what to do: draw a circle.
When we talk about commands and functions we realize something: they have a lot in common with algorithms. These are also a set of instructions that follow a certain order so they can work: if you don't write them in a certain order, you might not be able of drawing or creating what you want to.
Another concept we use, that we learned in class before, is the input and output. When we write the code, we are giving an input to the computer. The output is the result of our code, for example a line. The instruction we give is the input and the respond is the output.

We win points when we complete the activities given by KhanAcademy and the badges are given by different reasons which you can see in the photo below.

And thats everything. We hope you had a great time, see you next time!
